🏗️ Architecture

The project uses a frontend-backend separation architecture:

Components

• Web Client: Modern frontend application built with Vue 3 + Vite
• API Server: RESTful API service built with Gin framework
• Worker Service: Background task processing service for executing user-submitted code
• PostgreSQL: Persistent storage for code and execution results
• Docker: Provides secure code execution environment

📋 Prerequisites

• Go 1.24.2 or higher
• Docker and Docker daemon
• PostgreSQL database (optional, for production)
• Node.js and npm (for frontend development)

🚀 Quick Start

1. Clone the Repository

git clone https://github.com/dreamstarsky/runbin.git
cd runbin

2. Install Dependencies

# Install Go dependencies
go mod download

# Install frontend dependencies
cd web
npm install
cd ..

3. Setup Database (Optional)

If using database storage, create the database and run migrations:

# Create database
createdb runbin

# Run migrations
psql -d runbin -f migrations/0001_init_pastes.sql
psql -d runbin -f migrations/0002_create_queue_table.sql
psql -d runbin -f migrations/0003_add_compilelog_column.sql

4. Configure Services

Edit the configuration files:

API Service Configuration (config/api.yaml)

app:
  env: "release" # release or debug
  port: 8080

storage:
  type: "database"  # memory or database
  database:
    dsn: "host=localhost port=5432 user=postgres password=password dbname=runbin sslmode=disable"

Worker Service Configuration (config/worker.yaml)

storage:
  type: "database" 
  database:
    dsn: "host=localhost port=5432 user=postgres password=password dbname=runbin sslmode=disable"

limit:
  time: 10.0      # Max execution time (seconds)
  cpu: 1.0        # CPU limit
  memory: 512     # Memory limit (MB)
  size: 1024000   # Output size limit (bytes)

process: 1        # Number of worker processes

name: "default name"
  
compilerimage: "cpp_gcc-latest:latest"  # Compiler image

5. Start Services

Start API Server

go run cmd/api/main.go

The API server will run at http://localhost:8080.

Start Worker Service

go run cmd/worker/main.go

Start Frontend Development Server

cd web
npm run dev

The frontend will run at http://localhost:5173.

🐳 Docker Deployment

Frontend Web Deployment

The frontend supports Docker deployment:

cd web
docker build -t runbin-web .
docker run -d -p 80:80 -e BACKEND_URL=http://your-api-url:8080 runbin-web

For detailed frontend deployment instructions, see web/README.md.

Note

: API and Worker services do not currently support Docker deployment. Please run them directly with Go.

🔧 Development Guide

Adding New Language Support

1. Add a new task processor in Worker (refer to internal/worker/RunCppTask.go)
2. Prepare the corresponding Docker image
3. Configure the compiler image in worker.yaml
4. Update the supported language list in the controller

Local Development

# Start API in development mode
go run cmd/api/main.go

# Start Worker in development mode
go run cmd/worker/main.go

# Start frontend with hot reload
cd web && npm run dev

Build for Production

# Build API
go build -o bin/api cmd/api/main.go

# Build Worker
go build -o bin/worker cmd/worker/main.go

# Build frontend
cd web && npm run build

🔒 Security

• All code executes in Docker containers, isolated from the host
• Configured resource limits (CPU, memory, execution time)
• Output size limits to prevent malicious code
• CORS configuration to protect API access
